函数名称：store_cpumask

函数原型：static ssize_t store_cpumask(struct padata_instance *pinst, struct attribute *attr, const char *buf, size_t count)

返回类型：ssize_t

参数：

类型参数名称
struct padata_instance *pinst
struct attribute *attr
const char *buf
size_tcount
877  如果非分配CPU掩码则返回:负ENOMEM
880  ret等于bitmap_parse(buf, count, cpumask_bits - get the bits in a cpumask*@maskp: the struct cpumask ** You should only assume nr_cpu_ids bits of this mask are valid. This is* a macro so it's const-correct.(new_cpumask), nr_cpumask_bits)
882  如果ret小于0则转到:out
885  mask_type等于如果非字符串比较则PADATA_CPU_SERIAL否则PADATA_CPU_PARALLEL
887  ret等于padata_set_cpumask: Sets specified by @cpumask_type cpumask to the value* equivalent to @cpumask
888  如果非ret则ret等于count
891  out :
892  释放CPU掩码
893  返回:ret
